Donper newest products arrived, Donper self-developed enhanced vapor injection low temperature air source heat pump and floor heating optimizing combined system, the COP of this system can reach up to 3.0 in cold areas in winters, comfortable floor heating and domestic hot water work separately, Smart temperature control can meet different temperature requirements for every room, Unique pipeline anti-freezing technology ensures the whole units work smoothly. This application of air source heat pump achieve success in floor heating industry.

Ultra-low temperature air source heat pump is designed specifically for cold areas. Supply for domestic and commercial heating and domestic hot water, etc. It has excellent low temperature heating performance, adopted Enhanced Vapor Injection compressor, which break through the technical difficulties of normal air source heat pump, which ensure the heat pump can function well in-20℃. The system works in high efficiency, brings more comfort and safety , is suitable for northern areas as heat source for floor heating replacing the traditional central heating or gas boiler system to heat the rooms.

Product Features:

Power saving:Adopted new ASHP（air source heat pump)+solar heating technology, when inlet air temperature is 7℃, COP is above 3.2, The power consumption is 1/3 of electric heating.

2.Above data is based on theoretical calculating, please refer to the actual costs.

Narrow the diameter of heating pipe, reduce the distance between the heat pipes, increase the pipes density, to increase theheatdissipationarea and decrease the heating medium temperature（＜50℃）, reduce the water supply and backwater’s temperature difference（＜5℃）, make the temperature curve more flat and lower heat loss.

Refrigerating fluid as medium for ASHP, the low vaporization temperature of refrigerating fluid, vaporized at -40℃, therefore, there is temperature difference between inside and outside, refrigerating fluid is vaporized after absorbing outside temperature, and turned into HPHT(High temperature and high pressure gas) after heating by compressor, and exchanges heat with water by exchanger, and then relief pressure through expansion valve, returned to the liquidation of low temperature and low pressure, water in the tank is heated by refrigerating fluid cycled constantly and exchange heat with water. Keeping the water of constant temperature in the tank, heat exchanger connect with indoor floor heating system to cycle and exchange the heat, automatic temperature control indoor. Floor heating circulation water is separated with domestic hot water, will not affected the usage in life.
